Longitudinal vibrations in piano strings [PDF]
The Journal of the Acoustical Society of America, 1987 The percussive excitation of a piano string by a hammer is expected to produce longitudinal string vibration components in addition to the desired transverse ones [e.g., Yanagisawa et al., J. Acoust. Soc. Jpn. 33, 412–416 (1977)]. However, so far little quantitative information exists in current acoustics literature on the contribution of such ...

LONGITUDINAL-FLEXURAL SELF-SUSTAINED VIBRATIONS OF NANOTUBE CONVEYING FLUID
East European Journal of Physics, 2018 Beam model of geometrical nonlinear longitudinal-flexural self-sustained vibrations of nanotube conveying fluid is obtained with account of nonlocal elasticity. The Euler-Bernoulli hypotheses are the basis of this model.
